Honolua Bay - surf spot statistics

Best Surf Season (October - March)

The North Pacific roars to life during these months, delivering a consistent barrage of groundswells that light up Honolua Bay's northwest-facing reefs. Average wave heights range from 1.5m to 2.0m, with periods often exceeding 11 seconds, reaching into the 12-13s range during peak winter. Swell directions are dominated by the NNW-N-NW quadrant – exactly what this bay needs. Wind patterns shift favorably, with offshore winds from the S to WSW quadrant occurring 24-30% of the time, often triggered by passing cold fronts or high-pressure systems south of the islands. When the trade winds ease or back around, the bay transforms into a world-class, barreling left. This is prime time.

Fair Surf Season (April & September)

These transitional months offer a mixed bag. April still holds onto some winter energy, with average swell heights around 1.7m and periods near 10.6s, though the swell direction shifts increasingly east-northeast, reducing the number of perfect NW-N exposures. The trade winds (ENE) become more dominant (over 60%), making offshore wind windows harder to catch – only about 20% ideal wind. September marks the reverse transition: the first north Pacific storms stir, sending initial pulses of N-NNW swell (3.8-9.3%) while the persistent ENE trades begin to weaken. Ideal wind percentages climb back to 30%, offering occasional magic days with clean, long-period lines.

Low Surf Season (May - August)

Summer sees the North Pacific storm track retreat, and Honolua Bay relies on weak, short-period trade swell from the ENE and E. Average heights drop to 1.3-1.4m, and periods sit in the 8-10s range, often delivering weak, bumpy waves. The predominant ENE trade winds blow over 70% of the time, creating onshore or cross-onshore conditions that spoil what small swell does arrive. The bay becomes a flat, blown-out disappointment for months on end. Surfable days are rare, requiring a lucky break in the wind or a tiny south-swell wrap, but generally, it's a time to explore other breaks or take a break yourself.

July: Peak Summer Flatness

July continues the summer lull with the lowest average period of the year at 8.8s and a height of 1.3m. Swell is almost entirely from the ENE (62.8%) and E (27.9%), completely missing the bay's optimal window. The trade winds are at their strongest, with ENE dominating 73.8% of the time. Ideal wind plummets to just 17%. Honolua Bay is flat or blown out on all but the rarest of days – this is a month for leaving the board at home or chasing south shore waves.
